Letters Patent No. 100,058, dated February 22, 1870.

IMPROVED RAILWAY OIL-CAB.

The Schedule referred to in these Letters Patent and making part of the some.

' To whom it may concern.-

- Be: it known that we, S. W.-MnnnAY and.B. P.' .LAMAsQN, of the borough of Milton, inthe county.

of Northumberland, in the State of Pennsylvania,

' have invented a new. and useful Improvement in Rail I section of one half of the car.

Figure 2, a plan, showing one half of car frame and mode of constructing the same.

' Figure 3', a'transverse section. v Figure- 4, a, section of man-hole and cover.

Figure 5, a s ection" of body-bolster, showing irn proved king-bolt and mode of constructing bolster.

Figure 6 is a detached view of the tube M, in crosssectiou, and the bent hooks T.

We use in the construction of our car frame a combination of wood and iron, as shown in fig. 2, in which- A A are wooden stringers, extendingfull length of car-body audframed into end sills B B.

' Insteadof the wooden side sills ordinarily used in the construction of car bodies, we use iron tubes, seen at M M. These tubes are of the same length as the stringers A A, and are provided with cast washers on men ends. These washershave a bearing against the wooden end sills B B.

-An iron rod, Y Y, passes through the tubesM M,

which rods also extend through the end sills B B, and

have on their ends screws and nuts, and these nuts being tightened, the car frame-is compactly drawn together. I

N N,=&c., are cast-iron brackets, which are firmly secured to springers A A by means of rods and bolts. The tubes M M pass through these bracketsnnd 'are supported by them.

as to conform in shape, &c., totank A, as seen in D E D are timbers which form thebody-holster. The timbers I) D are also concave, like cross-beams O C. These all being uniform in shape. and arrangerent, they form a rack or cradle, in' which thetnnk A rests, andis secured in place by means of the iron straps 1 I, seen in figs. 1 and 3. r

F is a, substantial end cross-beam, framed into stringers A A. Theinside of this beam is carved out so as to conform to shape of tank-head.

the two end beams-F. The interstices between tank- -hcads and cross-beams F are firmly packed with oakurn or some other suitable material. This pairing is to 'prerentt-he tank from moving longit udinally,aud

thereby preserve it from injury wheniu actual scr-v vice.

and bolsters.

Z Zarc strong rodsextending back through bodybolster. These rods having on their outerends screws and nuts, and tberebeingtightened, the frame at this point is compactly drwn together.

Fig. 3 shows a transverse section of car frame and tank. A, tank, as in place, resting in cradle formed by concave cross-hea'ms'O O and bolster-timbers The tank isseonred in place by the iron straps I.

' A A are wooden stringers.

M M, iron tubes.

- N Roast-iron bracketsse'cured'to stringers A A. These brackets support the iron floor and also the hand-railing post S S.

Fig. 4 shows man-hole and cover. B, cover, 0',

base. This device is designed to admit person in and out of oil-tank, and it is also used for the purpose offilling the tank. It is composed of cast-iron or any other suit-able metal, and a thread is turned on the inside of base 0', the top edge of which is smoothly faced off.

It is then secured to tank by means of rivets, a hole of the proper shape and size having been previously cut in shell of tank A The man-hole cover 13' has an outside din-meter correspondingwith' inside diame-- ter of base 0', and a thread is turned on outside circumference of cover. A flange of proper width extendsbeyond the screw on cover, which is faced 0d, and a dovetail-shaped grooveis turned into it. -Into this groove we insert lead or any-other suitable ma terial, and this lead, being held in place by the pectliar form of the groove, when properly faced on", forms the packing E. This packing projects a little below the face of the flange. When the cover B is screwed down in place in base 0 by means of a. lever placed between the lugs L L, the projecting edge of packing coming in contact with the faced edge of base-O,

forms a perfectly oil-tight joint. The mac-hole cover.

When the tank A is in position on car ti'arne'it fits in between G is a longitudinal brace extending from one sill B bacleto holster, hailing its ends framed ints end sills? I I I are struts fitted in between cross-beam F and end sill B.

B is attached tobase O by means of the iron ring D passin arouud'and in the grooved periphery, of the nge. The ends of ring D are secured by a bolt to the chain" F; and the whslt firmly secured to base (Y-by ineans of the eye H'- A section of-body-bolster is shown in fig. 5. It is constmcted of three pieces-of timber, 1) E D, securely bolted together andlramed into the stringers A A.

V'representsour improved king-bolt its applied to. oil and other cars. King-bolts are ordinarily constructed with. the head at thetop end, and the bolt is passed down through body and truck-bolsters, the head resting on the upper side of car floor. We construct our improved kin'gboltby ibrming a collar near the middle of bolt, seen at V. This collar rests between the center plates W and X, and hence, sportionof both passes up into the body-holster and a portion down into the truck-bolster. We claim this to be a decided improvement over the usual mode of constructing and applying khig-bolts in railroad ca 5. The advantage claimed is that the king-bolt can be removed when desiized'withoutdistnrbing the tank.

.It also hasthe advantage, when applied to box'and other cm, of doing away with the necessity of perforating the car floor, thereby avoiding the losing of" gminswhen transported in bnl Fig. 1 represents the car complete ready for use.

8 S are iron posts supporting hand-railing. These posts are provided with an eye at top end through which railing R passes. Thebase's of posts are pro- .vided with screws and nuts, and being made ota suitable form they pass through the ends of brackets N.

The not coming on the under side, it is tightened and the posts S are thus held firmly in position. I T '1, 8m, are hooked" bolts which pass around the tubes M nt and up thmugh'the iron floor U. By this device the floor is firmly. secured to tubes. The floor U is also secured to iron brackets, N and 0, by means of rivets, and to the timbers composing'the car frame by screws and bolts. I

V shows the improved king-bolt in position. W and X are top and bottom center-plates. Having thus described our improvement, its conf attraction and operation, What we claim as our invention, and desire to secure by Letters Patent, isv 1. In combination with the wooden center-frame, of the car body, the brackets N, and side tubes M, coin structed and arranged substantial] y as andfor the put pose herein set forth. v

2. The dovetail packing E, substantially as de-. scribed. A

3. In combination withthe brackets N, the ironposts 8, and hand-railing Br, constructed substautiull y as and for the purpose herein described. a

4. The ring D, in combination with the cover B" provided with a grooved periphery. and attached to the tank by any suitable means, substantially as herein described.
